Who am I? ✨

My name is Trey and I help professional programmers improve their Python skills. I do on-site and remote Python training for teams and corporations and I run a Python skill-building service for individuals called Python Morsels.

I write articles regularly at If you'd like to keep up with my writing, sign up for my email newsletter. You can also find me on Twitter as @treyhunner.

The best way to improve your skills is to practice. It's hard to practice unless you have a regimen and a routine. Making a practice routine on your own is time-consuming and hard.

Python Morsels can help! Through Python Morsels, every Monday I send out one Python exercise. These exercise are meant to help professional Python programmers to hone their skills, not brand new programmers. They've been described as "Kreutzer's etudes for Python" and "like a reverse code review".

I send out the exercise on Monday morning which includes a base problem, bonuses, and automated tests to run against your code. The exercise should take you up to 30 minutes. On Wednesday I send out an email explaining different solutions for the exercise and why we might choose one technique over another.
